Sorry don't have any experience to share about
Aza effecting liver. My liver blood tests have not budged at all since I have been on it, about
a year now. If I understand correctly they will take you off of it, take the blood tests again and maybe go at a lower dose once the values normalize. If that fails they will take you off of it completely and probably suggest the biologics like Humuira and Remicade.
Sorry about not being of more help.
